borceux – Diagram macros by François Borceux
The macros support the construction of diagrams, such as those
that appear in category theory texts. The user gives the list of
vertices and arrows to be included, just as when composing a
matrix, and the program takes care of computing the dimensions of
the arrows and realizing the pagesetting. All the user has to do
about the arrows is to specify their type (monomorphism, pair of
adjoint arrows, etc.) and their direction (north, south-east,
etc.); 12 types and 32 directions are available.
